As part of maybe starting a project for a CMS + static site generator I decided to create a library that allows similar CSS pre-processing as Sass/SCSS. It’s not yet finished but it already works for most part (it’s missing the ability to create ad-hoce functions) and similar in many aspects to Sass, with the exception that it allows using EEx code blocks and arbitrary Elixir terms as assigns (on top of normal string based “variables”).
It also has a basic watcher that pre-processes your CSSEx files automatically and it’s made in a way to accommodate the needs I imagined for the possible CMS+SSG (programatically pass variables & assigns while generating css, etc).
You can check it at GitHub repo
Along with some basic examples.
As it is still lacking what is described in the roadmap I haven’t put it on hex yet, nor done proper benchmarks with more than small toy sized sass/cssex files, but in those cases I did it was fairly faster.
If you give it a try or have suggestions, bug reports, or want to contribute open an issue on the repo!
If you would like to see it in Erlang help me solve the issue of the EEx blocks and how to pass assigns into them - having that solved would allow to write it almost as is in Erlang (I also have no idea if anyone writing erlang needs a css preprocessor to be honest…)
(forgot to put on the readme but it also supports of course the “&” nested notation of sass)
